BYD's 1.5 four — BYD472QA naturally aspirated, BYD472ZQA turbocharged — in the Qin, the Song and the DM-i cars built on them.
⚑ In a DM-i car this engine rarely drives the wheels. BYD's plug-in system runs the engine as a generator across most of its operating range, so it spends its life at a narrow band of load and speed — which changes what wears and makes mileage a poor guide to its condition.
The naturally aspirated 472QA runs the Atkinson cycle for efficiency, which gives it modest output and unusual low-speed behaviour if it is ever asked to drive directly.
The Z is the turbocharger, and the turbocharged version is the one used where the engine does drive the wheels.
It is not the BYD476ZQA, which is also a 1.5 turbo, also petrol and has its own page here. Two BYD 1.5 turbos with adjacent numbers is exactly the shape that sends a parts order to the wrong engine — the 472 is the DM-i generation, the 476 the one before it.
English-language service material barely exists. BYD's own documentation is the practical source, and the engine is young enough that no independent failure pattern has established itself.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
